Here’s this afternoon’s MODIS Lake Michigan satellite picture. Note the ice on the west edge of the lake (which has appeared to be pulling away from shore this afternoon. The ice has shortened the distance that the air travels over open water by about 20 miles (so that means a little less lake-effect. The wind is west-southwest and where the air is missing Lake Michigan it’s sunny (generally south of a line from Benton Harbor to just south of Lansing. Despite the sunshine, it’s been colder there. The warming effect of the sun is less than the warming influence of Lake Michigan. Winds should be brisk tomorrow and strong on Thursday, so that will help to break up the ice on the Great Lakes. Downwind from the lake, we may get another inch or two of snow tonight into tomorrow morning north of a line from S. Haven to Middleville to Rockford to White Cloud. It’ll stay dry tonight into tomorrow morning along and south of I-94. Snow Thurs. PM will be heavier from Muskegon north along the lake, where 4″ could fall. Snowfall amounts will taper to an inch for Battle Creek, Jackson and Coldwater. It’ll be windy, with some drifting tomorrow, and a lot of drifting on Thursday. It’ll be better to do errands Thurs. AM rather than PM when the snow moves in. The Saturday snow will be the opposite, with heavier snow south and southeast (3-4″) and less snow north of Muskegon (maybe an inch). The big weather story could be a storm for the middle of next week. The models are variable and we’ll know more when the system gets into the balloon data out west over the weekend, but you’ll want to stay up with later forecast updates on that. The cold air is relentless with the GFS plot showing colder than average temps. thru the 2nd week of February. Here’s the MODIS pic. of Lake Superior, Lake Erieand Lake Ontario.
